Returns a table with new columns specified by the DAX expressions.
The table to which new columns are added.
The name of the new column to be added.
The expression for the new column to be added.
A table with all its original columns and the added ones.
ADDCOLUMNS does not preserve the data lineage of the added columns, even though a column expression is a simple column reference.
-- ADDCOLUMNS is an iterator that returns its first argument -- after adding the column specified. -- New columns are computed in the row context of ADDCOLUMNS, -- you need to invoke context transition to generate a filter -- context, if needed. EVALUATE FILTER ( ADDCOLUMNS ( VALUES ( 'Date'[Calendar Year] ), "@Year Number", INT ( RIGHT ( 'Date'[Calendar Year], 4 ) ), "@Amount", [Sales Amount], "@Quantity Wrong", SUM ( Sales[Quantity] ), "@Quantity Correct", CALCULATE ( SUM ( Sales[Quantity] ) ) ), [@Amount] > 0 )
|Calendar Year||@Year Number||@Amount||@Quantity Wrong||@Quantity Correct|

Best Practices Using SUMMARIZE and ADDCOLUMNS
Everyone using DAX is probably used to SQL query language. Because of the similarities between the Tabular data modeling and the relational data modeling, there is the expectation that you can perform the same operations as those allowed in SQL. However, in its current implementation DAX does not permit all the operations that you can […] » Read more
